1. A transversely divided last, a kerf in the adjacent end of each part, the kerfs off` the two parts being arranged to register, bonding means pivotally mounted at each end in said last parts, and interlocking, members positioned one in each of said kerfs provided with s oulders arra ged to positively interlock when the parts are in len thened position and with curved guiding ec ges arranged to when the last. parts are in shortened position and a spring tending to force one member toward the other.
